Device operations are selected by writing specific ad-
dress and data sequences into the command register.
Writing incorrect address and data values or writing them

read mode. Table 4 defines the valid register command
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the
Sector Erase operation is in progress.
